Sans possesses beastly powers. The source of them comes from Gaster, since both are fused. He has the ability to summon normal and purple bones, which are stronger, plus, they are extremely large. He can summon Gaster Blasters (which here are called Epic Blaster), which have a strange shape and are so strong that they generate explosions capable of destroying cities (With only 3 I can do it, plus they are huge). He is able to turn the soul of his enemy blue to move it wherever he wants and he can also use energy attacks that come out of his hands, sending his opponent flying far away and thanks to his speed he is able to dodge any attack. He is aware of timelines, AU's and resets, as well as being able to use shortcuts and teleport. He himself mentions that if he is not careful, he could destroy the underground. Despite having the same STATS as Chara, he is much MUCH stronger, which she (Chara) cannot cope with.

The weapon he mainly uses is his giant knife which he can enlarge, knives can appear instead of Gasters Blasters but he still has the abilities of the original Sans, his Gasters Blasters vary in color in the comic being blue and in the YouTube series red with a large x, his bone attacks are phosphoryloch orange (phosphorescent), his hp is not really defined since it has been seen that if he poose part of the soul of another being it is as if it does not affect him but the being from which he snatched that part of soul and finally he has the ability to steal the code of an Au and pass it to another (this thanks to Chara).
